Can the Diameter Final unit indication avp be used over Gx interface?
I know its available over Gy, but can I use it between pcrf and pcef?

YES
Take a look in the GX specification 29212-b70. If you look at the CCR you can find Charging-Rule-Report AVP. This is a grouped AVP that includes Final-Unit-Indication AVP.
Yes, As per Gx reference point (3GPP specs 29212 v13.5). Charging-Rule-Report AVP contains the Final-Unit-Indication AVP. It indicates the termination action the PCEF applies to the PCC rules.
